Saif al Islam Gadhafi, the second eldest son of Libyan leader Col. Moammar Gadhafi, visited the boy in the hospital along with airline chairman Capt. Sabri Shadi, according to a statement on Afriqiyah Airways' website.

More than two thirds of the passengers killed in the plane crash were Dutch, the foreign ministry said. Passengers from Libya, South Africa, Belgium, Austria, Germany, France, Zimbabwe and Britain were also among the victims, the airline said on its website.

The plane, an Airbus A330-200, departed Johannesburg, South Africa, and was at the end of its nearly nine-hour flight when it crashed.

Officials recovered the plane's flight data recorder, but investigators are still trying to determine what caused the crash.
